I have a DSL-2750B B1 product on firmware AU_2.05.
(I upgraded to 2.07, but it didn't fix the problem).
I have set up a schedule from 2am - 9am.
Under parental controls I have added a rule to block a MAC address based on that schedule.
At 2am access is not blocked.
The modem time is correct.
The PC is set up with a DHCP reservation using it's MAC address. I have confirmed the PC is getting the correct IP address. The settings on the PC are set to DHCP. The MAC address is not spoofed.
I'm damned if I can figure out why this is happening.
There are two machines at least that this appears not to work on. They are both Windows 8 that I upgraded over Christmas. I will test some windows 7 machines tomorrow, but when all PCs here were on windows 7 it was working fine.
Are there any know issues with Windows 8 and this DLink product?
Any ideas?
